What's with the bilstein on the lf?? Also would not hurt having alittle more rear percent.

Typically you dont want to run gas pressure shocks like a bilstein with a non pressure shock like an afco or pro. On top of that the 3050 is an easy up shock and would prob do you more good onthe RF than the LF.

I assume those scale numebrs are with driver in the car?

More rear would help. On a 2 link car 59-60%(without driver) isnt uncommon.

A few other things to try:
1050 pullbar spring
more LR bar angle
less RR bar angle
more pullbar angle
move pullbar to the left on the rearend
less rear stagger

how much fuel in tank ? if not full try more. also easy up shock on rt front will transfer more weight on left rear under acceleration. make a stick guage in 5 gal. increments. you can tighten up or loosen up car with fuel this way

We run 57% rear, and 50.5% cross, works great (on hoosiers). I believe the higher the rear %, the higher you need to raise your cross. I personally would leave rear alone, just increase your cross. Let your LR tire take you out of the corner.

Thanks for all the info, Yes we did scale car with driver in it and full of fuel. We put the bilstein on the LF to help transfer weight to RR. We have all the angle we can in the LR bar.

I agree with rear% and cross. I was always told rear percentage and cross should be directly proportional, i.e.; the more rear you run the more cross you should have. JMO good luck!

I do not have a calculator in front of me but looking at your wheel weights it looks like you have more x in it than 48.5%. trying to transfer the weight to the rr would make it looser coming out of the corner if it still layed over on rr coming out.

x did not look right but I added wrong in my head. the wheel wieghts thru me off. I am use to setting my car with wheel wieghts that are close up front like 550 lf and 525 rf .720lr 640rr
